Dl-Alaninium iodide.

ABSTRACT: The crystal structure of dl-alanine hydro-iodide (1-carb-oxy-ethanaminium iodide), C(3)H(8)NO(2) (+)·I(-), is that of an organic salt consisting of N-protonated cations and iodide anions. The compound features homochiral helices of N-H?O hydrogen-bonded cations in the [010] direction; neighbouring chains are related by crystallographic inversion centers and hence show opposite chirality. The iodide counter-anions act as hydrogen-bond acceptors towards H atoms of the ammonium and carb-oxy groups, and cross-link the chains along [100]. Thus, an overall two-dimensional network is formed in the ab plane. No short contacts occur between iodide anions.

dl-Asparaginium nitrate.

Project description:In the title compound, C(4)H(9)N(2)O(3) (+)·NO(3) (-), alternatively called (1RS)-2-carbamoyl-1-carboxy-ethanaminium nitrate, the asymmetric unit comprises one asparaginium cation and one nitrate anion. The strongest cation-cation O-H?O hydrogen bond in the structure, together with other strong cation-cation N-H?O hydrogen bonds, generates a succession of infinite chains of R(2) (2)(8) rings along the b axis. Additional cation-cation C-H?O hydrogen bonds link these chains into two-dimensional layers formed by alternating R(4) (4)(24) and R(4) (2)(12) rings. Connections between these layers are provided by the strong cation-anion N-H?O hydrogen bonds, as well as by one weak C-H?O inter-action, thus forming a three-dimensional network. Some of the cation-anion N-H?O hydrogen bonds are bifurcated of the type D-H?(A(1),A(2)).

dl-Asparaginium perchlorate.

Project description:Two enantiomeric counterparts (l- and d-asparginium cations related by glide planes) are present in the structure of the title compound, C(4)H(9)N(2)O(3) (+)·ClO(4) (-), with a 1:1 cation-anion ratio. The structure is built up from asparginium cations and perchlorate anions. In the crystal, mol-ecules assemble in double layers parallel to (100) through N-H⋯O, O-H⋯O and C-H⋯O hydrogen bonds. In the asparginium layers, hydrogen bonds generate alternating R(2) (2)(8) and R(4) (3)(18) graph-set motifs. Further hydrogen bonds involving the anions and cations result in the formation of a three-dimensional network.

dl-Tyrosinium chloride dihydrate.

Project description:In the title compound, C(9)H(12)NO(3) (+)·Cl(-)·2H(2)O, the cation has a protonated amino group resulting from proton transfer from chloridric acid. The structure displays double layers parallel to the [010] direction held together by N-H?O, N-H?Cl, O-H?O and O-H?Cl hydrogen bonds. These layers are stacked along the c axis at b = 1/2; within each layer, the tyrosinium cations are arranged in an alternating head-to-tail sequence, forming inversion dimers [R(2) (2)(10) motif]. The water mol-ecules allow for the construction of a three-dimensional hydrogen-bonded network formed by centrosymmetric R(6) (6)(28) and R(8) (8)(34) motifs.

DL-Methionyl-DL-Methionine/DL-Methionine Supplementation Alleviated the Adverse Effects of Dietary Low Fishmeal Levels on Growth and Intestinal Health of <i>Micropterus salmoides</i>.

Project description:DL-methionyl-DL-methionine (AQUAVI® Met-Met) (Met-Met) (0.10%, 0.20%, 0.30%, and 0.40%) or DL-methionine (DL-Met) (0.10%, 0.20%, 0.30%, and 0.40%) were added to a low-fishmeal diet in an attempt to reduce fishmeal in the diet of Micropterus salmoides (M. salmoides). The fish were randomly allocated into ten experimental groups (n = 100), each with 4 replicates of 25 fish (16.39 ± 0.01 g) each. Compared to 25% FM, 0.40% of DL-Met and 0.10% of Met-Met promoted growth, and 0.10% of Met-Met decreased FCR. Compared to 25% FM, the supplementation of Met-Met or DL-Met improved the intestinal antioxidant capacity by upregulating the NF-E2-related factor 2-mediated antioxidant factors and enzyme activities and nuclear factor kappa-B-mediated anti-inflammatory factors while downregulating the pro-inflammatory factors, thereby exerting anti-inflammatory effects. Moreover, 0.10% of the Met-Met diet affected the Firmicutes-to-Bacteroidota ratio, increased the levels of Proteobacteria, changed the composition of intestinal flora (Roseburia, Lachnospiraceae_NK4A136_group, and unclassified_Oscillospiraceae), and enhanced intestinal dominant bacteria (Caldicoprobacter, Pseudogracilibacillus, and Parasutterella), leading to improved gut health. In summary, the supplementation of DL-Met or Met-Met alleviated the adverse effect of fishmeal reduction (from 40 to 25%) on the growth performance and intestinal health of M. salmoides.

Structure and interstitial iodide migration in hybrid perovskite methylammonium lead iodide.

Project description:Hybrid perovskites form an emerging family of exceptional light harvesting compounds. However, the mechanism underpinning their photovoltaic effect is still far from understood, which is impeded by a lack of clarity on their structures. Here we show that iodide ions in the methylammonium lead iodide migrate via interstitial sites at temperatures above 280?K. This coincides with temperature dependent static distortions resulting in pseudocubic local symmetry. Based on bond distance analysis, the migrating and distorted iodines are at lengths consistent with the formation of I2 molecules, suggesting a 2I-?I2+2e- redox couple. The actual formula of this compound is thus (CH3NH3)PbI3-2x(I2)x where x?0.007 at room temperature. A crucial feature of the tetragonal structure is that the methylammonium ions do not sit centrally in the A-site cavity, but disordered around two off-centre orientations that facilitate the interstitial ion migration via a gate opening mechanism.

3-Carbamothioylpyridinium iodide.

Project description:In the crystal of the title salt, C(6)H(7)N(2)S(+)·I(-), inversion-related cations form an R(2) (2)(8) dimer linked by a pair of N-H?S hydrogen bonds. Pairs of iodide anions are located between adjacent cation dimers and are linked to them by way of N-H?I hydrogen bonds. This results in zigzag chains propagating in [001] lying parallel to the bc plane.

Melaminium iodide monohydrate.

Project description:In the title melaminium salt, 2,4,6-triamino-1,3,5-triazin-1-ium iodide monohydrate, C(3)H(7)N(6) (+)·I(-)·H(2)O, the components are linked via N-H?O, N-H?N, O-H?I and N-H?I hydrogen bonds. All of the H atoms of the melaminium cation are involved in hydrogen bonds. The melaminium cations are inter-connected by four N-H?N hydrogen bonds, forming ribbons along [111]. The water mol-ecules connected by N-H?O hydrogen bonds also form part of these ribbons. The ribbons are inter-connected by other hydrogen bonds (O-H?I and N-H?I), as well as by ?-? inter-actions [centroid-centroid distance = 3.6597?(17)?Å].
